I had a soft 13 and drew a soft 18 in difficult mode. The dealer's up card was a 3. The correct play, I believe, should be stand (Las Vegas multiple deck).Hit-or-Stand told me I should have doubled on the Soft 18...

Should you hit or stand on a 3-card soft 18 when the deaer shows 3,4,5,6?

Double if you can. If not, at least hit it.

A soft 18 against a dealer upcard of a 3 is such an advantageous situation, that you want to get as much money on the table as possible. It is so advantageous for you, that doubling, and taking just ONE more card, is the correct play. But if you can't double, then at least do the next best thing and STILL take another card.

Put it another way... if taking another card and doubling your bet is best, surely taking another card (but not doubling) can't be wrong! What's important here is to take another card.

Again, BlackJack Ed, that logic is wrong and completely flawed, and you should probably stop posting it in every single thread! ;)

There are several situations in which you double if you can but otherwise stand. Just because doubling is preferable doesn't automatically mean you should hit if you can't double.

If you have A,7 and the dealer is showing 2-6, you should double, but if you can't double (i.e.: A,2,5 or A,3,4), you should stand.

In addition, if you have A,8 and the dealer is showing 6, you should double, but if you can't double, you should stand.

The reason your logic is flawed is because you're missing the concept of doubling. For instance, let's say your odds of winning a hand are 75% if you stand or 70% if you hit. Obviously, if you can only play one hand, you want to stand. But, if you have the option to double, even though it lowers your odds of winning, your odds are still closer to that 75% than they are to even, so you'll make more money by doubling (and getting twice as much money into those still-great odds) than by standing.
